This cell formed near the New Mexico state line and moved to the northeast through northern Andrews County then into southern Gaines County. After crossing into Gaines County the storm, although small, developed a strong mesocyclone, and showed a classic hook echo on radar. About 6 miles south of U.S. Highway 180 and 3 miles west of the Dawson County line, a tornado formed. The tornado displayed a classic funnel shape with a relatively thin condensation funnel to the ground. The tornado eventually dissipated about 1 mile west of the Dawson County line still about 3 miles south of Highway 180.The tornado travelled across open lands with the only damage reported being the roof taken off a shed and shingles taken off a house. The house was thought to have not taken a direct hit. This damage was near the point of tornadogenesis.The storm began to weaken as it entered into Dawson County.
